Title: Compressible ply for printing blankets
Inventor: CASTELLI FRANCESCO
IPC: B29C35/02
Filed: 1993-03-24
Granted: 2006-09-26
Abstract: A laminated printing blanket (5) having compressible and resilient properties and a method for its production are provided. The compressible characteristics are provided by disposing an intermediate layer (10) having substantially uniformly distributed voids (30) of substantially uniform size between the base ply (25) and the working surface (15) of the printing blanket. The voids (30) of the compressible intermediate layer (10) are formed by introducing high melting point microspheres formed from thermoplastic resins into an elastomeric matrix (35), coating said microspheres containing elastomeric matrix (35) upon an upper surface of the base ply (25) and then vulcanizing the coated base ply at a temperature of between about 80-150 °C for between about one and six hours to form the compressible layer having substantially uniform compression characteristics. Once all of the layers of the blanket are stacked, a final vulcanization treatment completes the curing of all the layers to produce a laminated printing blanket.

Filed: 1994-11-28
Granted: 1997-11-18
Abstract: A unitary, insulated panel is provided for use in sectional doors and walls. The panel comprises opposed, spaced apart, parallel, inner and outer metal skins. The skins are mechanically interlocked along their top and bottom ends byintegral, inwardly projecting flanges having mutually engaged, hook-shaped terminal portions. The opposed flanges at each end are coplanar. The engaged hook-shaped terminal portions combine to form a longitudinally extending slot. The mouth of the slot is narrow relative to its bulbous inner portion. A strip of weather seal can be inserted longitudinally into the slot, for sealing purposes. Foamed polyurethane is formed in situ in the space between the skins. The polyurethane bonds to the skins. A rigid, strong panel unit is obtained by the combination ofmechanically interlocking the skins and bonding them with the core.

Title: Syntax parser for a video decompression processor
Inventor: HOOGENBOOM CHRIS
IPC: H04N7/50
Filed: 1995-10-04
Granted: 2001-06-12
Abstract: A video syntax parser is provided for a video decompression processor.  A compressed bitstream is examined until a start code is located.  The start code is decoded to enable a particular parser state corresponding thereto to be initiated.  The parser state is communicated to a plurality of subsystems of the video decompression processor.  Each subsystem monitors the parser state to determine which parsed data following the start code, if any, is intended for that subsystem.  The subsystem then retrieves the parsed data it requires via a data bus which receives the parsed data from the parser.

Abstract: Les différences de rendement d'un cylindre de criblage effectuant le criblage d'une suspension de fibres (par exemple de la pâte de papier de faible consistance) entre l'extrémité d'entrée et par rapport à l'extrémité de sortie sont adaptées par la construction de la surface d'admission du cylindre de criblage de telle sorte qu'une turbulence plus grande soit créée au voisinage de la surface contiguë à l'extrémité de sortie du crible qu'au voisinage de l'extrémité d'admission. Généralement, cette augmentation des turbulences est d'au moins 10 % environ (de préférence d'au moins 40 % environ et, généralement supérieure à 100 %). Cette augmentation des turbulences peut être obtenue grâce à une surface du milieu de criblage essentiellement lisse à l'extrémité d'admission et une surface du milieu de criblage relativement tortueuse à l'extrémité de sortie ou bien au moyen de surfaces dont la première et la seconde présentent des reliefs d'une aggressivité différente. Ces surfaces en relief comportent essentiellement des rainures, tandis que les éléments modifiables pour influer sur les turbulences sont la profondeur des rainures, l'angle d'inclinaison de la paroi de ces rainures en aval, l'espacement de ces rainures, le rayon de courbure des rebords d'ouverture (orifices ou fentes), la fréquence des ouvertures dans les rainures et les dimensions des ouvertures (orifices ou fentes) dans les rainures. Le cylindre de criblage est monté dans un boîtier de criblage pressurisé.
